Summer at northern hemisphere. Many players do post that they have no wifi.
3G data roaming costs can be too much for many of us, but how much data is transferred when you take a turn.
Launch Outwitters - who's turn is info loaded.
Open a match: some data loaded.
Send turn: data is sent.

Can this be measured somehow?
Can OML give us approximately some kind of data amount that we can count cost of playing Outwitters when data roaming.

EU has set price caps for data roaming, lower fares EU wide from July 1st, 2014..

If you go to settings, general, usage, cellular usage, and reset your stats and turn off wifi, you can open OW and play a game to check and compare.

That's 0,24 euros plus sales tax for roaming inside EU.
I pay 3,90 euros (including tax) for unlimited 3G data inside Finland.
And if we take a look how much iOS games cost to buy, roaming is not cheap...
or it does cost quite a bit to take a Outwitters turn (compared to how inexpensive purchase the game was).
